Question, are user created characters from video games acceptable? Like the main character from TES oblivion or dark souls?

That depends. Are you using cannon weapons? how closely are you going to refrence this game? and how strongly will its storyline affect your style of play?
If you answered yes to the first question, then no.
If you answered 'if you played the game you'll understand" to the second one, then no.
If you answered "Plot based quests will probably play some part in my history/bio" then no.

So, you can use say a D&D char, or something and whenever you cast a spell you explain what the hell the effects are I probably won't care. However if you pick say...a fable 1 char and reference the Archdeacons armor, and chrono-lock and the blade of souls then I'll probably tell you to take a hike. 
Simply put, if someone who hasn't played the game can understand it and it isn't cliche then I don't mind.
